As part of my interest to be able to more accurately monitoring my AMG GT engine oil level and related oil temperature control I got a spare oil reservoir.
I hereby share some of my findings after I made some observations and taken some pictures using the spare reservoir.
I'm inviting comments from others that may find this information useful to them.
I understand/see that pulling the drain plug with the engine oil at the normal working temperature and the in tank oil level at its highest will create a siphon effect in feed and oil return line.
I may look into a substitute (besides the original one) oil dip stick that can be used to check the oil level when the engine is cold
Hi Hendrik,
I like your reports. Always interesting. Outside the box. Thank you.
Do you mean checking the oil level when it is cold? Then you just have to subtract the heat expansion of the oil.
In any case, you have to let the engine run for about 1 minute. There will always be oil running back into the engine.
How much this is depends on the duration of the standstill. The non-return valve is not a 100% leakproof component.

Maybee I misunderstood something?

Hi Stenzel,
Thanks you, your one of the participants here that always has great input/feedback and I appreciate that. Yes the factor of the oil heat expansion (depending on temperature and time) are there, are you saying that if the car sits overnight all the oil out of the reservoir runs back into the engine? I'm planning to check this with an alternate dip stick that will go down to the very bottom of the tank.
When you say the non-return valve do you mean to say it's a one way valve?

Again thanks for your input, much appreciated.

Hi Hendrik,
That's exactly what I mean.Every dry sump lubrication normally has a one way valve in the inlet of the oil pump.This is near the oiltank lowest point, and the oil tank is usually higher up.Otherwise the oil would flow back into the engine.It can be tight, it should, but it is not always.
When I want to check the oil level, I don't know it. Therefore, let it run for a moment, then everything is where it should be.
The return pump, (Often there are several, that suck off at different points), usually have at least 2 - 4 times as much throughput as the feed pump.
A short engine run is completely sufficient.
Suggestion: Drive until your oil has reached temperature (here is 100 degrees Celsius), possibly fill up to the maximum. Next day., cold oil, short engine run, check. Due to the expansion, you must now deeper on level. Remember this fill level, and you have your future cold oil level control.

Stenzel - This is interesting information. I will try this.
